Description

Technical Field

[0001] The present invention relates to the technical field of steel structure processing, and particularly relates to a turnover fixture for steel structure processing that prevents shaking. Background Art

[0002] A steel structure, simply speaking, is a structure composed of steel materials. It is mainly made of sections and steel plates to form components such as steel beams, steel columns, and steel trusses. These components or parts are usually connected by welds, bolts, or rivets. Due to its excellent performance, the steel structure has an irreplaceable position in modern architecture and is widely used in skyscrapers, large-span stadiums, power plants, coal washing plants, material yard storage, gas stations, and residential buildings, etc. There are multiple processing processes for steel structures, and special turnover fixtures are required during processing to facilitate their processing.

[0003] For this reason, the patent with the publication number CN216582731U discloses a turnover mechanism for steel structure processing, including a processing table. An adjustment groove is opened in the upper right part of the processing table. An adjustment device for fixing steel structures of different lengths is movably connected between the middle of the left groove wall and the middle of the right groove wall of the adjustment groove. A fixing frame is fixedly connected to the middle of the upper end of the adjustment device and the upper left part of the processing table respectively. A cylinder is fixedly connected to the middle of the upper end of each of the two fixing frames. The output ends of the two cylinders respectively penetrate the upper shelf walls of the two corresponding fixing frames and are fixedly connected with a turnover device for adjusting the angle of the steel structure. A controller is fixedly connected to the upper left part of the front end of the processing table. The disclosed turnover mechanism for steel structure processing can fix steel structures of different lengths by setting the adjustment device, expanding the application range of the device. By setting the turnover device, the automatic turnover of the steel structure can be realized, improving the practicability of the device.

[0004] The above-mentioned turnover mechanism for steel structure processing can fix steel structures of different lengths by setting the adjustment device, expanding the application range of the device. However, the steel structure itself has a certain weight.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1-11, a anti-shake turning fixture for steel structure processing provided by the present invention, includes a frame body 1 and a moving mechanism 2 installed on one side thereof. A bracket 3 is provided at the top of the moving mechanism 2. Bases 6 are installed at the tops of the frame body 1 and the bracket 3. Turning mechanisms 5 are installed at the tops of the bases 6, and limiting structures 4 are connected to the opposite sides of the turning mechanisms 5; the moving mechanism 2 includes a gear set 21, a lead screw 22, a slide table 23 and a servo motor 24. The slide table 23 is installed on one side of the frame body 1. The lead screw 22 passes through the middle of the slide table 23. The lead screw 22 is threadedly connected to the slide table 23. A servo motor 24 is installed on one side of the lead screw 22, and a gear set 21 is installed on one side of the servo motor 24 and the lead screw 22;

[0034] Refer to Figure 1 and Figure 2 As shown in

[0035] When the device is in use, place the steel structure in the L-shaped grooves of the two connecting pieces 41, and then start the servo motor 24 to drive the gear set 21 to rotate, so that the lead screw 22 rotates. The lead screw 22 is threadedly connected to the slide table 23. When the lead screw 22 rotates, it pushes the slide table 23 to slide inward along the frame body 1, driving one connecting piece 41 closer to the other connecting piece 41, making it the same length as the steel structure, realizing the support of the steel structure, and being applicable to steel structures of various lengths;

[0036] Refer to Figure 3 , Figure 6 and Figure 7As shown, when the device is in use, rotate the rotating sleeve 431 so that the limiting block 433 rotates to correspond to the side wall of the connecting piece 41, and there is a certain distance between the sleeve 431 and the connecting seat 45. Then, push the limiting plate 42 downward. Through the sliding between the slider 44 and the connecting piece 41, the limiting plate 42 slides to the position closest to the steel structure. Then, flip the limiting shaft 43 so that the magnet on one side of the sleeve 431 corresponds to the position of the magnet in the limiting hole 434, and adsorption is generated to achieve fixation. Then, rotate the handle 432 to drive the limiting shaft 43 to rotate. The bottom of the limiting shaft 43 fits with the hexagonal groove at the top of the limiting plate 42, and the limiting shaft 43 rotates and inserts downward into it. Then, push the limiting plate 42 continuously downward to longitudinally press and extrude the steel structure. Moreover, the limiting shaft 43 and the connecting seat 45 are threadedly connected and fixed by threads, which is more firm;

[0037] At both ends of the bottom of the connecting piece 41, pressing plates 423 are provided. On both sides of each pressing plate 423, push rods 422 are hinged. At the top of each push rod 422, a connecting rod 424 is hinged. At the bottom of the connecting piece 41 where the push rod 422 and the connecting rod 424 are connected, limiting grooves 421 are installed. At the connection of the push rod 422 and the connecting rod 424, a hinge shaft is provided, and the hinge shaft and the limiting groove 421 form a sliding structure. At the top of each connecting rod 424, a connecting block 425 is hinged, and a sliding structure is formed between the connecting block 425 and the limiting plate 42. At the opposite ends of the connecting block 425, first springs 426 are installed;

[0038] Refer to Figure 6 、 Figure 7 and Figure 11 As shown, when the device is in use and the limiting plate 42 is pushed to clamp the steel structure, the top of the push rod 422 is driven by the connecting rod 424 to slide downward along the limiting groove 421. Thus, the inclination angle of the push rod 422 gradually becomes smaller, and the pressing plate 423 is pushed to squeeze towards the middle position, realizing centering positioning of the steel structure and limiting it from the side to enhance the stability of fixation. When the pressing plate 423 centrally clamps the steel structure and the limiting plate 42 is still being pressed downward continuously, the first spring 426 is used to relieve the force, so that the connecting block 425 squeezes it. The first spring 426 is an alloy spring steel and has a high anti-pressure effect. While being able to push the steel structure to be centered, it plays a role in relieving the force when it cannot move;

[0039] The flipping mechanism 5 includes a cylinder 51, a support 52, a chute 53, a rack 54, a spur gear 55, a snap ring 56 and a connecting shaft 57. The chute 53 is installed at the top of the base 6. A rack 54 is provided at the top of the chute 53, and a sliding structure is formed between the rack 54 and the chute 53. A cylinder 51 is installed on one side of the rack 54, and one end of the cylinder 51 is connected to the rack 54. A support 52 is installed on one side of the rack 54, and a connecting shaft 57 is installed inside the support 52. The connecting shaft 57 is connected to the connecting piece 41. A spur gear 55 is installed on one side of the connecting shaft 57, and a snap ring 56 is provided inside the spur gear 55. The spur gear 55 and the rack 54 are meshed and connected. A baffle 522 is provided on one side of the support 52, and a sliding structure is formed between the baffle 522 and the support 52. Second springs 525 are installed at both ends of the baffle 522. A pull ring 523 is installed on one side of the baffle 522. Movable plates 521 are installed at both ends of the rack 54 on one side of the pull ring 523. A push plate 524 is provided inside the support 52 on one side of the baffle 522, and a latch 526 is provided on one side of the push plate 524. A third spring 527 is installed on the other side of the push plate 524;

[0040] Referring to Figure 4 , Figure 8 , Figure 9 and Figure 10 As shown, when the device is in use, after the steel structure is fixed, two cylinders 51 are started simultaneously to drive the rack 54 to slide along the chute 53. When the number of teeth on the rack 54 moves, the spur gear 55 meshed with it rotates 180°. At the same time when the sliding of the rack 54 ends, the movable plate 521 on one side of it pushes the pull ring 523 to drive the baffle 522 to slide towards one end. When the rack 54 stops, the baffle 522 moves to the outermost end, and the latch 526 inside it loses its limit and quickly pops out under the tension of the third spring 527 to achieve snap-limiting of the snap ring 56. When the steel structure processing generates shaking, it can protect the spur gear 55 and the rack 54, avoid wear of the teeth after long-term use, and extend their service life. When it is necessary to flip again, pull the push plate 524 to drive the latch 526 to slide into the inside of the support 52, and then start the cylinder 51 to drive the rack 54 to move again to achieve flipping. When the rack 54 moves to drive the movable plate 521 away from the pull ring 523, under the action of the second spring 525, the baffle 522 is driven to reset to block and limit the latch 526 again, and the staff can release the push plate 524.
